1. total distance traveled varies directly with the amount of time spent traveling. if traveling 4.5 hours results in 180 miles traveled, write the direct linear variation equation. then determine how long it would take you to travel 320 miles, assuming you traveled at the same rate.
a.what are the variables (the input and output)?
b.solve for k.
c.write the direct variation equation.
d. how long will it take you to travel 320 miles?

Ответ:
Statement 1: The GCF of the numbers in each term in the expression is 2.
Statement 3: The factored expression is 2 (6 d minus 13 c).
Step-by-step explanation:
12d: 2 × 2 × 3 × d
26c: 2 × 13 × c
GCF: 2
12d - 26c
2(6d - 13c)
